I've been experiencing some serious wacky problems after a fresh installation of windows xp pro sp2 (which is now sp3). I just fixed a lot of drivers and other problems now im just left with the first problem i started with. Slow boot up, startup, and shut down. Not only that The sound has been completely choppy esp. on startup and any media (mp3, audio, video , flash etc.) On top of that i've been trying to fix this driver "SM bus controller" with a question mark in device manager. when i uninstall it, it comes back when i restart and unsuccessfully installs. i've tried reinstalling chipsets, audio drivers etc.... If theres any info u need just ask me thanks in advance
